We fetch this document again every day and compare it with the version we verified; if the district changes it, the dates here are read again.

Note: Document does not say whether it is board-approved, so status is unknown. The Mar 29-Apr 2 week is marked only as local recess (not named Spring Break); it is entered as spring break based on the dates. The Thanksgiving and winter breaks are also unnamed. Oct 2 is a Staff Development Day and Oct 30 is Parent Conf TK-12 (Student free); both are treated as no school for students, consistent with the October count of 20 student days. Total of 180 instructional days is the sum of the monthly student-day counts on the grid, not a stated total. Minimum days: TK-5 on Oct 27-29 and Mar 2-4 (parent conferences); Grades 6-12 on Oct 29 (parent conferences); Grades 9-12 on Dec 17 and Jun 2; Grades 6-8 on Jun 2; TK-12 on Dec 18 and Jun 3 (last day). A floating minimum day for Grades 9-12 is shown in May with the date TBD. The grid marks the Grades 6-12 quarter/semester ends and the Grades TK-5 trimester ends. The format of secondary parent conferences is a site-based decision. Aug 13 is a teacher work day (no school) and Aug 14 is a half teacher work day (no school), both before the first day.
